Background: The study aimed to observe the internal structure of coconuts from two locations (coastal and non-coastal) using computed tomography (CT).
Methods: Seventy-six mature coconuts were collected from Wenchang and Ding'an cities in Hainan Province. These coconuts were scanned four times using CT, with a two-week interval between each scan. CT data were post-processed to reconstruct two-dimensional slices and three-dimensional models. The density and morphological parameters of coconut structures were measured, and the differences in these characteristics between the two groups and the changes over time were analyzed.
Results: Time and location had interactive effects on CT values of embryos, solid endosperms and mesocarps, morphological information such as major axis of coconut, thickness of mesocarp, volume of coconut water and height of bud ( < 0.05).
Conclusions: Planting location and observation time can affect the density and morphology of some coconut structures.

The synthesis of Carbon Quantum Dots (CQDs) from agro-waste supports United Nations Sustainable Development Goals 3, 9, 12, and 13, offering a sustainable approach to environmental and healthcare challenges. Dried coconut leaves (DCL), abundant agro-waste from the Kongu region of Coimbatore, Tamil Nadu, India, serve as a carbon-rich precursor for CQD synthesis. The DCL is carbonized at 300 °C for 2 h, producing spherical, semi-crystalline CQDs with an average particle size of 15.

() is a critical transcription factor that plays a significant role in regulating plant growth and development. Mining the coconut SPL family offers valuable insights into the regulation of important agronomic traits, including the length of the juvenile phase. In this study, 25 were identified and were classified into eight subfamilies.

Bis(2-ethylhexyl) phosphate (P204) is widely used in extraction processes in the nuclear and rare earth industries. However, its high solubility in water results in high levels of total organic carbon and phosphorus in aqueous environments, and may also lead to radioactive contamination when it is used to combine with radionuclides. In this paper, we characterized a coconut shell activated carbon (CSAC) and a coal-based activated carbon (CBAC) for the adsorption of P204 and then evaluated their adsorption performance through batch and column experiments.

The present study focuses on the synthesis of coconut shell-derived biochar (BC), molybdenum disulfide (MoS), and poly(acrylic acid) (PAA) (BC/MoS/PAA) composite. The composite was synthesized a simple hydrothermal method. The structural and morphological features of the resulting composite were thoroughly characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), Brunauer-Emmett-Teller (BET) surface analysis, and Raman spectroscopy.

MFeO (M = Co and Mn) nanoparticles were synthesized from coconut coir extract using a microwave-assisted co-precipitation method, representing a green and sustainable approach for ferrite nanomaterial preparation. The physical properties of the samples were characterized using X-ray diffraction, scanning electron microscopy, ultraviolet-visible spectroscopy, photoluminescence, Raman spectroscopy, and vibrating sample magnetometry. Scanning electron micrographs revealed nanoscale morphology with evidence of polymorphism.
